f LUBRICATING AIPARATUS:

` Application led March 14', 1922, Serial No. 543,651. Renewed January'20, 1928.

This invention pertains to improvements in lubricating apparatus. It isyamo'ng the objects of the invention to prov1d e lubrifcating apparatus in which a lubrleant-reeeiving art may be quickly attached to and detached) `from a lubricant-expellmg, device while minimizing the opportunity for leakage or loss of lubricant. 1 Y v In the drawings, which showV apreferred form of one embodiment of my invention Figure 1 is a side elevation of a lubricantexpelling device engaged with a lubrlcantreceiving nipple; Q v

Fig. 2 is a central, longitudinal nsection through the nozzle portion of the device 1llustrated in Fig. 1, being partly in elevation;

Fig. 3 is a section on 2, showing the relation of the parts 1n coupled relationship;

Fig. 4 is a view similar to Fig. 3, showlng the relationship of the parts when unconp Fig. 5 includes an end and a side elevation of a preferred form of nozzle sleeve;

Fig. 6 includes an end and a side elevation of a preferred form of conneetlng'sleeve;

Fig. 7 includes a Side and an end elevation of a preferred form of sealing part,

Fig. 8 illustrates two cooperatlng valve parts, more fully described hereinafter; and

Fig. 9l is a section on the line 9-9 of Fig. 2.

Referring to the drawings and to the preferred'form of my invention selected for i1- lustrative purposes, I have showna lubricantexpelling device including the usual barrel 9 containing a plunger of the usual construction and actuated by a screw-threaded stem 10 engaging the `rear head 11 of the gun. At the discharge end of the gun, I have provided coupling means for 'engagement'iwith a iubricant-receiving nipple 412 having a lubricant-receivingpassage therethrough,which maybe sealed at its receiving end by the usual check-valve 13. The nipple illustrated is provided with lateral pro'ections 14,' which in the construction il ustrated present a square like the head of a cap screw. The preferred form of coupling illustrated includes a nozzle part lpresenting at its end a square aperture 16 interiorly may underlie the the line 3 3 of Fig. f

cylindrical so as to provide flanges 17 which projections on the nipple when turned relatlve thereto. Vithin the nozzle` part or sleeve 15, I have provided a sealing part 20 movable toward and from the flanges 17 by inclined means typified by the screws 21, 21 engaging inclined slots 22 in the sleeve.

To permit turning of the nozzle sleeve without corresponding turning of the sealing part, I have provided a connecting sleeve 3 0, shown in detail in Fig. 6. having a squared Iaperture therein into which may tit the head of the lubricant-receiving nipple 12 and also a squared end 31 of the sealing part 20. By making the connecting sleeve.

30 separate from the sealing disc or ,part 20,I

I am enabled to maintain it always in engagement with the inner face of the flanges 17, so that there will be no opportunity foi" dirt or other foreign matter to get thereunder when the sealing part 20 is retracted and the lubricant nipple removed. The sealing part 20 is apertured at 32 to permit passage of lubricant therethrough, and, rearwardly of the sealing part 20, I have provided a chamber 33. The sealing part 20 carries a sealing washer 34 at the end next tothe nipple and preferably provides, as illus trated, a sealing washer 35 at its opposite end to prevent leakage between the sealing `part and the nozzle sleeve 15.

Considering the parts thus far described, it will be understood that when the nipple 12 is entered in the nozzle sleeve 15 and the nozzle sleeve 15 is turned, there will be no corresponding turning movement of the sealing part 20. because the connecting sleeve 30 opposes such turning movement, but the sealing part 2O will press the sealing Washer 34 against the lubricant-receiving face of the I nipple 12 while leaving the lubricantreceiving opening therein free to receive the lubricant through the passage 32 in the sealing part 20.

Cooperating with ythe parts hereinbefore described, I have provided valve mechanism controlling thel passage of lubricant to the coupling and, in that form of my invention illustrated, I have providedl coordinated means providing for deferred operation of the valve pursuantto coupling and for deferring the operation of the couplingmeans during uncojupling until after closure of theA valvey means. f

In the preferred form of my invention illustrated, I eiiect this by maintaining the valve parts in their closed position until `after coupling is e'ected and by then permitting opening ofthe valve without further movement oit4 the coupling parte.

Referring to Fig. 2 of the drawings, the,

coupling' sleeve 15 is connected to the barrel 9 through an outer sleeve 50 and clutch z means is provided opposing relative movement between thls outer sleeve andthe oou.

ling sleeve until after coupling is effected. he clutch means in question may take the form of the ball 51' (Fig. 4) 'which,vuntil coupling'is completed, is carried partly by the coupling sleeve 'but is pressedinto a notch 52 in the outer'sleeve by the outer wall of the sealing part 20, 'as viewed in Fig. 4.

' When coupling is ei'ected, the ball 51 will have been turned until itcomes opposite the depression 54 in the sealing part 20. |By

this time, the 4sealing Washer 34 will have been lsuiliciently pressed againstthe nipple to make a tight joint and the ball or clutch '51 will pass out. of the notch 52 inthe outer sleeve, permitting turning of the outer sleeve relative to the coupling-sleeve, as viewed in Fig. 3. Carried by the'oouplin sleeve 15,

i I have provided a valve part 55 ig. 2) and carried by the outer sleeve 50, I have provided a valve part 56. These valve parts, in

the form of my invention illustrated, are

turned .relative to one another to open the valve. Therefore, when the outer sleeve 50 turns relative to the coupling sleeve 15, the

arts of the valve illustrated will be brought 1nto linev (as shown in Fig: 2) so that lubricant may pass therethrough, and; to prevent further movementjo-f the Avalve 'art `56, I

yhave provided a slot 5? (Fig. 9) 1n the couing operations.

.means thereafter loc weaves direction, viz the direction' opposite to that which elected the coupling and'valve-opennot be'uncoupled until the valveis closed, because no relative turning movementv of the sealing disc and nozzle sleeve 15 can be effected until the outer sleeve has been turned suliiciently to permit the clutch 51 to come out of the recess in the sealing part 20 and into the recess 52 in the outer sleeve. l/Vhen this occurs, the valve will be closed and the outer sleeve and couplin sleeve willl turn together relative to the sea ing part 20 The coupling,'however, canuntil uncoupling is completed by ,retraction ofthe sealing part' 2O by operation of the pin and slot means 21, 22. During this retraction, the connecting sleeve 30 will not have retracted .because of itssliding engagement with the sealing part 20.

While I have shown anddescribed a preferred form of one embodiment of my inventon, it will be lunderstood. that changes involvingomission, substitution, alteration and reversal of parts, and even changes in the mode of operation', may be made without de parting Yfrom the scope of my invention, which is best defined in the following claims.

1. Lubricating apparatus including. a lubricant compressor havin 'a nozzle presenting .a valve part'and a sea lng part assembled y therewith reciprocable in said nozzle by rotary movement transmitted to said nozzle when engaged with a' lubricant receivin nipple, said valve independent of said sea ing part and disposed rearwardly thereof. 2.

In testimony whereof, I- havel signed my name to this specication. v
